Improvement in selvage and twine cutters



UNITED STATES PATENT OFFICEn CHARLES W. COLLYER, OF MARBLEHEAD,MASSACHUSETTS, ASSIGNOR TO HIMSELF AND FREDERICK W. MUNROE, OF SAMEPLACE.

IMPROVEMENT IN SELVAGE AND TWINE CUTTERS.

Specification forming part of Letters Patent N0. 153.539, dated July 28,1874 application filed May 18, 1874.

To all whoml t may concern:

Be it known that I, CHARLES W. COLLYER, of Marblehead, in the county ofEssex and State of Massachusetts, have invented an Improved Selvage andTwine Gutter; and I do hereby declare that the following, taken inconnection with the drawings which accompany and form part of thisspecilication, is a description of my invention sufficient to enablethose skilled in the art to practice it.

This invention is designed for a simple and handy implement for family,store-keepers, or manufacturers purposes, serving the double purpose ofa selvage or cloth trimmer, as well as a twine or thread cutter; and itconsists in making the same complete, including' its cutters, from asheet of metal cut and bent to shape, as hereinafter set forth.

In the drawings, A is a strip of metal, having two cutting-blades, b c,formed therein by cuts, made as indicated by the two lines x y and y .ein Fig. 2, the line x z remaining uncut. These tria-ngular pieces c' y zare then bent on the line a' e, so that they shall stand about at aright angle to the plane of the strip or plate, of which they are apart, as shown in Fig. l, and each, near its base-line, has a deep notchcut in its edge of a somewhat semicircular form, as shown at d d, Fig.l. The whole plate is bent or doubled transversely, as seen, so that thetwo cutters b and c shall be in close relative cutting position, and itis also bent in a reverse direction to form a hook,

e, to permit the implement to be hung in the button-hole of the coat orgarment, or inthe belt of a dress; and it has an opening therein, (shownat f,) whereby it may be screwed or otherwise permanently secured to atable, desk, or other xed object.

It will now be seen that when the material, whether a fabric or a twine,cord, or thread, is pulled inward against the inclined shearingedges ofb c, or if the edges be pressed toward each other like the blades of ashears, the article in ordinary cases must be severed; but if, by reasonof a perversity of the material, or any other cause, the inclined partsof the shears, may sometimes happen, allow the material to slip betweenthem without effecting a perfect cut, then it passes to the othercutters Z d', which, by reason of their different form, and becausetheir cuttin g-ed ges offer a more abrupt and positive resistance to thematerial, insure the cutting to a certainty, as they prevent any passingbeyond them of an unsevered article.

I claim- The described selvage and twine cutter constructed complete,including its cutters, from a single piece of sheet metal cut and bentto shape, as shown and set forth.

Executed this 13th day April, A. D. 1874.

C. W. GOLLYER.
